📏 Ttogle Ttogle Grading Criteria

Ttogle Ttogle is not an app for creating unique handwriting styles, but rather an app that corrects difficult-to-read handwriting into easy-to-read text. Scores are assigned based on objective criteria that affect readability, such as slant, letter ratio, size consistency, and letter spacing.

Therefore, even if your handwriting is distinctive and neat, it may receive a low score if it does not meet these standards.

The score is not the value of the handwriting itself, but a learning indicator showing "how close you have gotten to easy-to-read handwriting." If you revise your writing according to Ddogeuli's advice,

your score will improve, and in the process, your hand strength and readability will grow.
